Latest Patents
One of his latest patents is titled "Single stage pulsed domino circuit for driving cascaded skewed static logic circuits." This invention involves a complementary metal oxide semiconductor (CMOS) low-power, high-speed logic circuit that consists of a cascaded chain of stages. The first stage is a pulsed domino logic circuit that receives data signals and a clocking pulse, conditioning it for evaluation during a brief window of time. The output connects to a series of skewed static logic gates, which alternate fast transitions for the information-carrying leading edge of input data signals. This design reduces power consumption while maintaining the speed of conventional domino logic circuits.
Another notable patent is the "Low power precharge scheme for memory bit lines." This invention introduces a low-power memory bit line precharge scheme that utilizes a first read precharge device and a second write precharge device. The second device is enabled only during a memory write operation, ensuring that the combined drive strength is sufficient to precharge the memory bit line effectively.
